Description
本发明涉及一种院内设备查找的路径规划方法。
医院是诊断和治疗病人的地方；工作于医院中的医务人员凭借学识和经验，并借助医疗设备来完成对病人的诊断和治疗。随着科学的发展，医疗设备也不断发展，例如在现代医疗中出现了种类繁多的诊断和治疗设备，包括但不限于监护仪、红外温度计、呼吸机、麻醉机、心电除颤仪、超声设备、数字X射线成像设备、血液细胞检测设备、凝血分析仪和尿液检测设备等。
有一些医疗设备是大型的或不可移动的，因此被安装在一些专门的科室和房间内，例如床边监护仪、台式彩超设备、大型数字X射线成像设备、血液细胞分析仪、化学发光免疫分析仪、生化分析检测设备和凝血分析仪等；而有一些医疗设备则设计成小型化以便移动，具有便携性，例如转运监护仪、便携式除颤仪、红外耳温枪和便携彩超设备等。

步骤400：基于用户端的位置信息以及所述院内设备的位置信息，在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径。
在具体实现本发明时，可以在院内设置多个第一无线器，院内各设备则被设置有第二无线器，通过第一无线器与第二无线器的连接，服务器或用户端等具有计算能力的装置来计算院内设备的位置信息，以及获取院内设备的设备类型和/或设备标识等，这样就可以实现对院内设备的定位。需要说明的是，设备标识指的是院内设备的ID，例如可以是编号等，院内设备和设备标识是一一对应的关系；设备类型则是指院内设备的类型，例如设备类型为转运监护仪、便携式除颤仪、红外耳温枪和便携彩超设备等，因此通常设备类型对应着多个院内设备。
院内定位的具体方式下面试举几例。
例如本发明可以通过WIFI室内定位技术来实现院内设备的定位。一些实施例中第一无线器和第二无线器通过WIFI进行连接。在对院内设备进行定位时，基于院内设备的第二无线器与三个第一无线器的无线信号强度，通过差分算法，来比较精准地对院内设备进行三角定位。或者，可以事先记载巨量的各位置点的信号强度，通过当前院内设备的第二无线器的信号强度与事先记载的巨量数据进行比较，来确定当前院内设备的位置信息。
例如本发明也可以通过超宽带UWB室内定位技术来实现院内设备的定位。一些实施例中第一无线器和第二无线器是可以接收和发射具有纳秒或纳秒级以下 的极窄脉冲来传输数据的通信单元。在对院内设备进行定位时，利用事先布置好的已知位置的锚节点和桥节点，与当前院内设备进行通信，并用于三角定位技术来确定院内设备的位置信息，或者，也可以事先记载巨量的各位置点的信号强度，通过当前院内设备的第二无线器的信号强度与事先记载的巨量数据进行比较，来确定当前院内设备的位置信息。
例如本发明也可以通过蓝牙室内定位技术来实现院内设备的定位。一些实施例中第一无线器和第二无线器通过蓝牙进行连接。蓝牙室内定位技术与WIFI室内定位技术类似，只不过蓝牙室内定位技术利用的是蓝牙的信号强度，WIFI室内定位技术利用的是WIFI的信号强度，在此不再对蓝牙室内定位技术进行赘述。
例如本发明也可以通过RFID定内定位技术来实现院内设备的定位。例如一些实施例中第一无线器为RFID阅读器，第二无线器则为RFID标签，通过RFID阅读器可以读取RFID标签的特征信息，例如接收信号强度以及具有该RFID标签的院内设备的设备类型和/或设备标识等；再通过采用近邻法、多边定位法、接收信号强度等方法确定RFID标签或者说具有该RFID标签的院内设备的所在位置。
例如本发明也可以通过红外线室内定位技术来实现院内设备的定位，例如第一无线器为光学传感器，用于接收和感应红外线，第二无线器用于发射红外线；院内设备通过第二无线器发射调制的红外线，设置在院内的第一无线器则接收该红外线并转化成电信号，基于该电信号可以计算院内设备的位置。
在具体实施例中可以根据需求来选择采用现有技术或未来出来的室内定位技术，以实现获取本发明中院内设备的位置信息，实现对本发明中院内设备的定位。
实际情况中，用户有时只需要查找一个医疗设备，有时也需要同时查找多个医疗设备，本发明既可应用于用户查找一个医疗设备的情况，也可以应用于用户查找多个医疗设备的情况，因此在一些实施例中步骤100中院内设备查找请求可以用于查找用户所需的一个院内设备，在另一些实施例中步骤100中院内设备查找请求可以用于查找用户所需的多个院内设备，下面分情况说明。
在一些实施例中步骤100中院内设备查找请求用于查找用户所需的一个院内设 备，并且一些实施例中院内设备查找请求包含设备类型的信息和设备标识中的一者或两者。
一些实现方式中，用户端可以具有如图2(a)所示的输入框，供用户输入设备标识，其中每一个设备标识对应着一台具体的设备，这样用户通过输入设备标识，然后点击查找，就完成了院内设备查找请求的输入；图中显示的是输入设备标识为N22-001的例子。请参照图3，为路径规划方法的一种硬件实现的系统图，可称为路径规划系统。服务器等可定时获取院内设备的设备信息和位置信息，其中设备信息包括设备类型和/或设备标识等；这样当服务器通过用户端接收到院内设备查找请求时，基于院内设备查找请求所包含的设备标识，查找到相应院内设备的位置信息——例如当服务器接收到如图2(a)所示意的院内设备查找请求时，则服务器查找到设备标识为N22-001的位置信息。在查找到相应院内设备的位置信息后，又由于可以获取到用户端的位置信息，因此基于用户端的位置信息以及所述院内设备的位置信息，在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径，例如在预设的院内地图上规划从用户端位置到达用户所需的院内设备的路径，以使得该路径为最短路径或耗时最少的路径——例如仍以图2(a)为例，则规划一条从用户端到设备标识为N22-001的最短路径或耗时最少的路径。需要说明的是，图3中显示的是步骤400的路径规划是在服务器完成，然后服务器再将路径规划结果发送给用户端来显示，但是可以理解地，步骤400也可以是在用户端来完成，在这种情况下，服务器基于设备查找请求将获取的院内设备的位置信息发送给用户端，用户端再基于院内设备和自身的位置信息来完成路径规划。
一些实施方式中，用户端可以具有如图2(b)所示的选择框，供用户选择设备类型；图中显示的是用户选择了便携式除颤仪这一设备类型。同样地，服务器等可定时获取院内设备的设备信息和位置信息；这样当服务器通过用户端接收到院内设备查找请求时，基于院内设备查找请求所包含的设备类型，查找到该设备类型的院内设备的位置信息——例如当服务器接收到如图2(b)所示意的院内设备查找请求时，则服务器查找便携式除颤仪这一设备类型的设备的位置信息。在查找到相应院内设备的位置信息后，又由于可以获取到用户端的位置 信息，因此基于用户端的位置信息以及所述院内设备的位置信息，在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径，例如在预设的院内地图上规划从用户端位置到达用户所需的院内设备的路径，以使得该路径为最短路径或耗时最少的路径。需要说明的是，由于设备类型可同时对应着多个院内设备，因此服务器可能会同时查找到多个相同设备类型的院内设备的位置信息，所以在基于用户端的位置信息以及所述院内设备的位置信息进行路径规划时，可以是选择离用户端最近的一个院内设备进行路径规则，例如选择离用户端最近的一个院内设备在预设的院内地图上规划从用户端位置到达用户该院内设备的路径，以使得该路径为最短路径或耗时最少的路径；也可以是在预设的院内地图上规划从用户端位置分别到达各符合设备类型的院内设备的路径，然后从中选择一条最短或耗时最少的路径作为最终的规划路径。
在一些实施例中步骤100中院内设备查找请求可以用于查找用户所需的多个院内设备，并且一些实施例中院内设备查找请求包含设备类型的信息和设备标识中的一者或两者。
一些实现方式中，用户端可以具有如图4所示的界面，同一设备类型的院内设备被显示在一起，院内设备的设备标识前具有复选框，当复选框被勾选时则表示需要寻找该设备，用户通过勾选一个或多个设备标识前的复选框来选中相应的院内设备，再点击查找，就完成了院内设备查找请求的输入；图中显示的是用户勾选了设备标识为N22-002的转运监护仪和设备标识为BD-001的便携式除颤仪。同样地，服务器等可定时获取院内设备的设备信息和位置信息，其中设备信息包括设备类型和/或设备标识等；这样当服务器通过用户端接收到院内设备查找请求时，基于院内设备查找请求所包含的设备标识，查找到相应院内设备的位置信息——例如当服务器接收到如图4所示意的院内设备查找请求时，则服务器查找设备标识为N22-002的转运监护仪和设备标识为BD-001的便携式除颤仪的位置信息。在查找到相应院内设备的位置信息后，又由于可以获取到用户端的位置信息，因此基于用户端的位置信息以及所述院内设备的位置信息，在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径，例如在预设的院内地图上规划从用户端位置依次到达用户所需的多个院内设备的路径，以 使得该路径为最短路径或耗时最少的路径。
在一些实施例中，用户还可以通过选择图4中的设备类型前的复选框，来选择需要查找的设备类型，再点击查找，就完成了院内设备查找请求的输入。同样地，服务器等可定时获取院内设备的设备信息和位置信息；这样当服务器通过用户端接收到院内设备查找请求时，基于院内设备查找请求所包含的设备类型，查找到该设备类型的院内设备的位置信息。在查找到相应院内设备的位置信息后，又由于可以获取到用户端的位置信息，因此基于用户端的位置信息以及所述院内设备的位置信息，在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径，例如在预设的院内地图上规划从用户端位置依次到达用户所需的多个院内设备的路径，以使得该路径为最短路径或耗时最少的路径。需要说明的是，由于设备类型可同时对应着多个院内设备，因此当用户选择了多个设备类型进行查找时，服务器会针对每种设备类型查找出多个相同设备类型的院内设备的位置信息，因此在基于用户端的位置信息以及所述院内设备的位置信息进行路径规划时，得到的路径规划结果是从用户端出发的一条路径，该条路径会经过用户所需的每种设备类型中的一个设备。
在一些实施例中，本发明还实时获取用户端的位置信息；当确定到用户端已到达用户所需的其中一个院内设备时，重新获取剩余的用户所需的院内设备的位置信息，并重新规划从用户端的当前位置到剩余的用户所需的院内设备的路径，以使得该路径为最短路径或耗时最少的路径。
本领域技术人员可以理解地，图2和图4只是用户端接收用户输入设备查找请求的一些例子，并不用于限定用户端只能通过这些方式来接收用户输入的设备查找请求。
一实施例中，本发明在预设的院内地图上规划从用户端位置到达所述院内设备位置的路径中可以包括：在预设的院内地图上根据路径中包含的电梯、楼梯和/或当前时间来规划出一条路径，以使得该路径为最短路径或耗时最少的路径。
本发明通过绘制院内(例如医院)的地图，布置相应的定位装置(例如第一无线器和第二无线器)，院内设备将自身的标识和类型等设备信息定时发送给接收装置(例如第一无线器)，接受装置将接收到的设备信息和定位得到的位置 信息，定时发送给服务器，服务器接收到所有的院内设备的设备信息和位置信息后进行设备查找和路径规划等，医护人员可以根据设备类型和设备标识等信息快速查找检索相应设备，让医护人员尽快的找到对应的医疗设备，设备科的维修人员，可以一次性的找到所有的设备，并且制定最佳的检修路线。
本文参照了各种示范实施例进行说明。然而，本领域的技术人员将认识到，在不脱离本文范围的情况下，可以对示范性实施例做出改变和修正。例如，各种操作步骤以及用于执行操作步骤的组件，可以根据特定的应用或考虑与系统的操作相关联的任何数量的成本函数以不同的方式实现(例如一个或多个步骤可以被删除、修改或结合到其他步骤中)。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。另外，如本领域技术人员所理解的，本文的原理可以反映在计算机可读存储介质上的计算机程序产品中，该可读存储介质预装有计算机可读程序代码。任何有形的、非暂时性的计算机可读存储介质皆可被使用，包括磁存储设备(硬盘、软盘等)、光学存储设备(CD-ROM、DVD、Blu Ray盘等)、闪存和/或诸如此类。这些计算机程序指令可被加载到通用计算机、专用计算机或其他可编程数据处理设备上以形成机器，使得这些在计算机上或其他可编程数据处理装置上执行的指令可以生成实现指定的功能的装置。这些计算机程序指令也可以存储在计算机可读存储器中，该计算机可读存储器可以指示计算机或其他可编程数据处理设备以特定的方式运行，这样存储在计算机可读存储器中的指令就可以形成一件制造品，包括实现指定功能的实现装置。计算机程序指令也可以加载到计算机或其他可编程数据处理设备上，从而在计算机或其他可编程设备上执行一系列操作步骤以产生一个计算机实现的进程，使得在计算机或其他可编程设备上执行的指令可以提供用于实现指定功能的步骤。
虽然在各种实施例中已经示出了本文的原理，但是许多特别适用于特定环境和操作要求的结构、布置、比例、元件、材料和部件的修改可以在不脱离本披露的原则和范围内使用。以上修改和其他改变或修正将被包含在本文的范围之内。
前述具体说明已参照各种实施例进行了描述。然而，本领域技术人员将认识到 ，可以在不脱离本披露的范围的情况下进行各种修正和改变。因此，对于本披露的考虑将是说明性的而非限制性的意义上的，并且所有这些修改都将被包含在其范围内。同样，有关于各种实施例的优点、其他优点和问题的解决方案已如上所述。然而，益处、优点、问题的解决方案以及任何能产生这些的要素，或使其变得更明确的解决方案都不应被解释为关键的、必需的或必要的。本文中所用的术语“包括”和其任何其他变体，皆属于非排他性包含，这样包括要素列表的过程、方法、文章或设备不仅包括这些要素，还包括未明确列出的或不属于该过程、方法、系统、文章或设备的其他要素。此外，本文中所使用的术语“耦合”和其任何其他变体都是指物理连接、电连接、磁连接、光连接、通信连接、功能连接和/或任何其他连接。
具有本领域技术的人将认识到，在不脱离本发明的基本原理的情况下，可以对上述实施例的细节进行许多改变。因此，本发明的范围应仅由以下权利要求确定：
